Oil and gas productions yield a by-product designated as produced water (PW). The high oil content of this effluent prevents its disposal or reuse. This study presents a novel alternative for the removal of oil from produced water using saponified babassu coconut oil (SBCO), as the ionic surfactant part which captures the oil by micellar solubilization, followed by ionic flocculation with Ca²⁺ ions. A factorial experimental design was applied to optimize the oil removal (RE) process. The experiments investigated the influence of SBCO + CaCl₂ concentration, temperature (T), and stirring speed (ω). Extraction Percentages (RE) in the range from 64.901% to 88.444% were achieved. Subsequently, the influence of pH, CaCl₂/surfactant ratio and oil removal kinetics in the highest RE% system were evaluated, whereby for pH > 7, (calcium chloride/surfactant) ratio of 1:1, and 15 min of stirring, the RE obtained was 100%. The same maximum removal result was obtained using a microemulsion containing SBCO. Thus, it can be affirmed that the application of ionic flocculation using SBCO is an efficient technique in the treatment of PW.

石油和天然气生产产生的副产品称为采出水（PW）。该废水的高含油量阻止了其处置或再利用。这项研究提出了一种新的替代方法，即使用皂化巴巴斯苏椰子油（SBCO）从采出水中去除油，作为离子表面活性剂部分，通过胶束增溶作用捕获油，然后用Ca ²⁺离子进行离子絮凝。应用了析因实验设计来优化除油（RE）工艺。实验研究了SBCO + CaCl ₂浓度，温度（T）和搅拌速度（ω）的影响。提取百分比（RE）达到64.901％至88.444％。随后，pH，CaCl ₂的影响对最高RE％系统中的/表面活性剂比率和除油动力学进行了评估，从而在pH＞ 7（氯化钙/表面活性剂）比率为1：1且搅拌15分钟的情况下，获得的RE为100％。使用含有SBCO的微乳液可以获得相同的最大去除结果。因此，可以肯定的是，使用SBCO进行离子絮凝是处理PW的有效技术。
